Question

Natural numbers are always whole numbers

Answer 1

Yes, natural numbers are a subset of whole numbers. By definition, natural numbers are the positive integers starting from 1, which include numbers like 1, 2, 3, 4, and so on. Whole numbers, on the other hand, include all natural numbers and also the number 0. Therefore, all natural numbers are indeed whole numbers, but not all whole numbers are natural numbers since 0 is included in whole numbers but not in natural numbers (at least in the most common definition).
